I don't know what your specifications or design goals/objectives are but 4k7 for the diff amp emitter resistors seem quite high to me, even with a current mirror load. If you need to reduce transconductance so much, why not use cascoded JFETs?

I just copied the original circuit and made everything is working or worked , and jfets too costly in India and if I have to buy jfet then have lots of options or better amp to make , for me normal listening HONEYBADGER AND MX50SE 👍 BIPOLAR VERSION😊

Honestly jfet not available in Indian local market specially 2sk170 and actually I don't need jfet increase extra 2 or 3 digit of zero 0 in THD 🤣🤣
